Model Answer
Placenta is extremely essential for foetal development because:
- Nutrition: The embryo gets glucose and oxygen from the mother's blood through the placenta. Villi on the embryo's side provide a large surface area for this transfer.
- Waste removal: Waste substances produced by the developing embryo are transferred into the mother's blood through the placenta for disposal.
- Connection: It is a disc embedded in the uterine wall that links the mother's blood spaces with the embryo's villi, enabling exchange of materials throughout the approximately nine months of development.

Explanation
Examiners expect two to three distinct functional points about the placenta — nutrition (glucose + oxygen) and waste removal are the two core functions. Mentioning the structural detail (villi, blood spaces, large surface area) earns full marks. Avoid vague statements like "it helps the baby"; use precise terms from the textbook.
